101: Alex Gibney on how Theranos fooled Silicon Valley

HBO's documentary "The Inventor: Out for Blood in Silicon Valley" looks at the case of Elizabeth Holmes who created the company Theranos promising to revolutionize the field of blood-testing. The company swiftly rose to be valued at billions of dollars, but was eventually exposed as a fraud.

Host Thom Powers interviews director Alex Gibney and producer Erin Edeiken about the making of the film.
